Fix some cases of updating draw state while recording a BPicture

* Also implemented recording DrawString(string, length,
BPoint[] locations), which was previously not recorded at all.
* Also implemented playing back recently added drawing commands
in PicturePlayer.cpp. I don't quite understand what this is
actually used for, but it seemed it was forgotten. I just followed
the pattern already established in the code.
* The other important bit in this change is to update the pen
location when it is needed while recording a BPicture. Often
the BView will use PenLocation() in order to transmit drawing
commands to the app_server which use absolute coordinates only.
This isn't actually so nice, since it means the client has to
wait for the server to transmit the current pen location. If there
were dedicated link-commands for pen-relative drawing commands,
the client could just keep sending without waiting for the server.
In any case, the app_server needs to update the pen location in
the current DrawState and even the DrawingEngine even while
recording a picture, because some next command may need up-2-date
state information, such as the font state and the pen location.
* I have not yet tried to find /all/ instances where the DrawState
needs to be updated while recording. This change should repair
/all/ font state changes, all versions of drawing a string, and
all versions of StrokeLine().

BView: add methods for affine translation/scaling/rotation

* BView::TranslateBy(), BView::ScaleBy() and BView::RotateBy()
allow to conveniently modify the current affine transformation.
This makes it unnecessary to first read the current transform,
modify it, and then set it again.
Uses the new Pre...() methods of BAffineTransform.

* Also, remove setting the transform "through" to the BView even
while recording a BPicture, as this now results in transforms
being applied more than once.

app_server/Interface Kit: add new clipping API

* Add new clipping API for rectangles (ClipToRect, ClipToInverseRect)
and shapes (ClipToShape, ClipToInverseShape)

* Works with affine transforms and automatically switches from fast
region-based clipping to alpha-mask based clipping as necessary.

* Always self-intersecting, i.e. no state push required to further
narrow down the clipping region. All of the 4 new methods can be
mixed in any order.

Implement ClipToPicture inside a BPicture. Not working yet.
BView::ClipToPicture doesn't work anymore, when nested inside a BPicture,
This happened when its implementation was moved server-side.

PicturePlayer: Rework to be more safe against corrupted data.

This introduces a more sane API (currently private) that allows for
safer and possibly more efficient implementations:

* It uses a struct of named and typed function pointers instead of just
a void pointer array. This adds type safety to the callbacks so the
compiler can figure out if things match up before subtle bugs get
introduced.
* It provides bounds for all strings/buffers passed to the callbacks.
* It uses const references instead of implicitly copying arguments.
* It folds stroke_x/fill_x pairs into draw_x functions with a fill
argument to reduce the amount of functions needed.
* It uses unsigned values where negative values make no sense.

The old API has been implemented on top of the new one using adapter
functions. It makes copies of all data passed to the callbacks which
effectively keeps the picture data from being modified. This matches
with the R5 behaviour.

This also reimplements the buffer parsing to be safe against corrupted
data by validating that the types actually fit in the provided sizes
and buffers (using a templated reader).

Since this class is used from the app_server with user provided data,
making it more safe is important even though it comes with a slight
overhead (replicating R5 behaviour, i.e. crashing the app_server when
corrupted data is fed, doesn't seem very appropriate here).

* Rewrote BeBuild.h which had "a few" consequences (got rid of all those class
definitions).
* Minor cleanup here and there.

Moved the dummy table local to the PicturePlayer::Play() function since,
as Marcus pointed out, having it outside wasn't thread safe. Moved
PicturePlayer into the BPrivate namespace.

Added "const" to many parameters.
Removed most data allocations/copying from PicturePlayer, ServerPicture now has to do this when converting coordinates.
Added additional functions to ViewLayer to copy&convert multiple BPoint, BRect, BRegion to Screen coordinates, those should be further optimized.
Removed some function call overhead.
Note: some functions of PicturePlayer don't appear to be implented by PictureDataWriter,
